next()

next(int position)

Returns int

This function returns the next led compared to the one given in the argument, wrapping around if the 3rd led is given. next(0) returns 1, next(1) returns 2, next(2) returns 0.

Example:

int currentPosition = 0;

void loop() {

// if the button has been pressed

if (tlob.buttonPressed()){

// turn the current led off

tlob.led(currentPosition, LOW);

// switch currentPosition to next led

currentPosition = tlob.next(currentPosition);

tlob.led(currentPosition, HIGH);

}

// updates the button

tlob.update();

}
